In the given example the Event has been started by the PPV of 15.2 mm/s at
6.592 Hz. The PPV value meets the condition of Reduction Factor that has been
set to 0.5 as the value of 15.2 mm/s is at 50% of the L curve height at this point
(the L at 6.59 Hz is around 30.5 mm/s). SVAN 958AG stores the value that
triggered the Event as the Alarm value that can be displayed in +.
According to the
Event Duration
setting, the
Event lasts 4 seconds (stopped at 12:29:48). At
the Stop point the system analyses the 4
seconds of previous data to determine the Event
maximum PPV, which in this example is the
value of 15.2 mm/s at 6.592 Hz at the X axis.
